Manuelle Nachbearbeitung und Rework durch Spezifikationsverstöße (Kontaminationen)
Definition
Scrap grading requires removal of non-ferrous metals (copper, tin, lead, bronze), mechanical components (motors with Ni/Cr/Mo content), and other steriles before classification into standard grades (E3, E2, E6, E40). The BVSE specification explicitly prohibits: metallic copper, tin in any form, lead-based materials, materials with high dissolved copper (rebars), chromium/nickel/molybdenum alloys above tolerance. Manual hand-sorting (per Interco description) and mechanical separation fail to catch these in 5–10% of batches. Downstream rework involves re-processing: e.g., tin-can contamination requires burning hood operation (additional cost €50–€150/tonne), X-ray florescence to detect residual copper (€30–€80/sample), or manual de-tinning labor (€15–€45/tonne).
Key Findings
- Financial Impact: €15,000–€50,000/year per facility in combined rework labor, equipment operation, and lost margin. Typical scenario: 100-tonne batch contaminated with 2–5% non-ferrous metals = 2–5 tonnes requiring rework. Rework cost: €80–€200/tonne = €160–€1,000/batch. If 1–2% of batches are affected monthly (10,000-tonne/year facility = ~83 batches/month), that is 1–2 rework batches = €160–€2,000/month = €1,920–€24,000/year. Add customer deduction disputes: €5,000–€10,000/year in margin haircuts.
- Frequency: 1–3 contamination incidents per month per mid-size processor; cumulative rework cycle time 10–20 days per incident.
- Root Cause: Reliance on visual inspection and basic magnetic/mechanical sorting; no X-ray or eddy current detection of non-magnetic contaminants (copper, tin residue); inadequate staff training on BVSE specification compliance; batch mixing from commingled input sources.
